Letters Patent No. 90,820, dated Juncl, 1869.

IMPROVED SPRING-BED BOTTOM.

The Schedule referred to in these Letters Patent and making part of thesame.

ToA all whom fit/may concern:

Be it known that we J OHN L. Coornn and ELIAS A. MONROE, of the cityofEhnira, in the county of Oheinung, and State of New York, haveinvented certain Vnew and useful Improvements .in Spring-Beds; and we dohereby declare that the following is a full, clear, and exactdescription thereof, reference being had to the accompanying drawings,and to the letters of reference marked thereon, which form a part ofthis specication, and in which- Figure 1 represents a plan View;

' Figure 2, a side view; and

' Figure 3, an end view of our spring-bed.

Similar letters indicate like parts in all the figures.

Our invention relates to improvements in springbeds; and to this end,

It consists in the employment of wires for crossbars, by which means weare able to fasten all the v joints firmly without the use of rivets,making use of the springs -as fasteners, not only of themselves, but ofall the joints of the frame.

Our invention further consists in the use of crossrods or wires, at theend of the frame, by which the top of each end and side is fastened tothe bottom of each opposite end and side, the object of which will behereinafter fully described.

lTo enable others skilled in the art to which our in' vention appertainsto make and use the same, we will now describe its construction andoperation.

In the accompanying drawings- A represents the frame, which consists ofthe paralle] wires a a and the longitudinal wires b b. The parallelwires are first bent, at each end, over the edge of the frame, as seenin fig. 1. One end of the A longitudinal wires is then secured to theedge of the frame, and passed over the first parallel wire, under thenext, and so on to the end of the frame, where it i is secured by asimilar bend to the edge of the frame. It will be observed that thefirst longitudinal wire and every second one passes over the iirstparallel wire, while the remainder pass under the first parallel wire.By Vthis arrangement the wires are made partly secure.

B B represent spiral springs, the ends of which are `bent over the pointwhere the paralleland longitudinal wires cross each, other, as seen infig. l, whereby.

the springs B B, and the wires a a, b b, are secured without the use ofrivets, as is the case when iron straps are used.

D D represent diagonal wires, secured by a bend to the sides of theframe. These wires are placed at suitable distances apart, and are toprevent the bed from leaning over to either side.

E E represent similar diagonal wires, attached to the ends of the frame,to prevent the ends from leaning over.

Having thus fully described our invention,

What we claim, and desire to secure by Letters Patent, is-

A spring-bed bottom, consisting of frame A, 'parallel wires a a.,longitudinal wires b b, diagonal braces D D, E E, and spiral springs BB, the whole being constructed, combined, and arranged substantially asand for the purpose speciiied.

In testimony that we claim the foregoing .as our own, we our signatures,in presence of two wit nesses.
